ISO 6025:2000 PDF

This International Standard specifies basic technical characteristics for the international exchange of analogue photographic sound test films intended for checking, adjusting and measuring motion-picture projector sound systems and sound reproducing channels of motion-picture installations for monophonic or stereophonic reproduction.

This International Standard specifies types and technical characteristics of test films made on 35 mm and 16 mm motion-picture films.

This International Standard includes test films intended for the checking, adjusting and measuring of

• focusing and azimuth of the scanning beam,
• scanning beam width and its position relative to the reference edge of the film,
• uniformity of the scanning beam illumination,
• level output balance of several motion-picture projectors,
• frequency response of the sound reproduction channel, and
• non-uniformity of film travel.
